Kasey Palmer has returned to Huddersfield on a season-long loan until June 30, 2018, as the team prepares for the step up to the Premier League from the Championship.
The 20-year-old attacking midfielder makes the move from Chelsea having also spent last campaign at the John Smith's Stadium, scoring five goals in 26 appearances.
Huddersfield manager David Wagner said: "I'm very happy to have Kasey back at the club. As we know from last season, he's a very talented English player with high potential.''
